The equation for a linear regression takes the form
y = m*X + b
If you create a chart then add a linear trendline it will display both the slope(m) and the y-intercept(b) on the chart. Alternately, without creating a chart you can use the built-in statistical functions =SLOPE() and
=INTERCEPT() to calculate m and b.
The equation for an exponential regression takes the form
y = a*exp (b*x)
Again, I can create a chart and add an exponential trendline producing the equation showing the values of a and b.
However, I can’t seem to find any built-in statistical functions that will yield both a and b.
Do these functions exist?
